perf(statusbar): cache layout/scale derived data behind epochs (major)
...
Status bar rescanned the whole object map twice per frame (layout_names +
scale_picker_list), deep-cloned an already-cached Arc, and built two
undo/redo label vecs consumed ~never. Cache layout names (epoch key) and
scale picker (epoch + unit-factor + imperial-family + current-scale key)
as Arc behind choke-point invalidation (layout/scale impl methods,
undo/redo swaps, file-open, doc-reset); borrow across the widget boundary
(owned-Arc params; E0515 forbids &'a slices over call-site temporaries);
build undo/redo labels only when their dropdown is open.
Tests:
- cached_layout_names_returns_same_arc_until_bump: hit-path Arc identity
- cached_layout_names_invalidated_by_add_layout: bump yields new Arc + names
- cached_scale_picker_returns_same_arc_until_bump: hit-path Arc identity
- cached_scale_picker_invalidated_by_add_scale: bump yields new Arc + scale
- cached_scale_picker_invalidated_by_current_scale_change: key completeness
Bench (cargo bench ui_statusbar_derived_data, 3k entities): cached hit below
timer granularity vs ~1us uncached scans, PASS (50us threshold).

perf(plotstyle): extract and speed up layer-usage table rebuild
...
view_window() rebuilt the 256-bucket ACI layer-usage table inline on every
modal view: unconditional 256-Vec allocation plus sort_by_key (lowercase key
recomputed per comparison). Extract pure build_layer_usage(), build it only
when the CTB path needs it (STB path now allocates nothing), and sort with
sort_by_cached_key while skipping trivial buckets.
Tests:
- build_layer_usage_buckets_index_colors: ACI bucketing + case-insensitive order
- build_layer_usage_ignores_non_index_colors: truecolor layers excluded
Bench (cargo bench ui_plotstyle_layer_usage, 200 layers): ~13us median, PASS.
A/B vs pre-change inline code: ~15.7us -> ~12-13us (~22% faster).

perf(bench): introduce standardized 25-metric CAD and UI benchmark suite
...
- Add comprehensive performance benchmark harness in benches/performance_benchmarks.rs
configured with harness = false in Cargo.toml (runs via cargo bench in --release,
isolated from cargo test).
- Benchmark coverage across 25 distinct CAD & UI operations:
* Entity Ingestion, GPU Wire Partitioning, Analytical & Wide/Tapered Arc Tessellation
* 100x Zoom Navigation, Spatial InteractionIndex, Multi-mode Hit-Testing, OSnap Tracking
* 2D Parametric Dogleg Constraint Solving, DXF Import/Export Throughput
* UI Ribbon View Construction, Viewport Grid Projection, Grid Cache Evaluation
* Themed SVG Icon Lookup Caching, Cold Extents AABB Calculation
* Batch Entity Transformation, Draworder Depth Map Full/Patch, Delta-Undo Recording
- Expose internal calculation hooks with #[doc(hidden)] pub to prevent API leakage.
- Remove 644 lines of legacy, scattered ad-hoc #[test] #[ignore] benchmarks across src/.
- Add developer and regression documentation in benches/README.md.
